WATE R-IIOTOR.

To all whom it may concern:

Be it known that we, ANDREW J. MEMMEL and-EMIL E. MEMMEL, of Milwaukee,Wisconsin, have invented a WatenMotor, of which the following is aspecification.

Our invention has for its object to produce a water motor moreparticularly adapted for household operation and in small shops and thelike, to produce suflicientpower to run small machines, where cheapnessof installation is more esteemed than efliciency.

More particularly we aim to produce a water motor of sufiicient powerfor our purposes at a minimum of expense so that the motor can bemanufactured and sold on the market at a price so low as to be withinthe reach of anyone having use for an apparatus of this sort.

The construction and operation of our motor will best be understood froma consider ation of the following description of one specific embodimentthereof, reference being had to the accompanying drawings, whereinFigure 1 is a front elevation of the motor having the galvanized ironplate which forms the front closure of the casing removed to show theinterior, Fig. 2 is a side elevation of the motor showing the casing incentral section, Fig. 3 is a perspective view of one of the buckets orvanes of the motor.

In cheap motors as heretofore constructed it has been customary toconstruct them entirely of metal, which while it makes undoubtedly amore durable construction, is not necessary to accomplish the purposesin view and makes the cost of construction so expensive as to partiallydefeat its purpose. Our construction on the other hand is so devisedthat the body of the motor may be made of wood, although we do not limitourselves to wood as a material or to any special material ofmanufacture. The body a of the water-wheel may, however, convenientlyand appropriately be made of wood, and is flanked on either side by adiskshaped metal sheet I) which may be of galvanized iron, tin-plate orthe like, and the whole is solidly secured by means of screws or otherfastenings to a hub-piece c which may be appropriately of cast iron andprovided with a hub-sleeved, the whole mounted upon the motor-shaft eand secured thereto by means of a pin f driven as shown throughdiametral holes bored in the sleeve d and shaft 6. The shaft e ismounted to rotate in bearings g, which are mounted on Specification ofLetters Patent.

cross-bars h extending transversely across the center of the rectangularcasing i, which comprises a rectangular frame, preferably of wood,closed on its opposite faces by galvanized iron sheets j, as clearlyshown in Fig. 2. The shaft 0 is reduced at one end to form a shoulder7c, abutting against one side of the bearing-block g, while a collar Zfixed by a set-screw m forms an abutment or thrust-bearing 011 the otherside of the bearing-block, thus preventing end motion of the shaft inits bearings. On the opposite end of the shaft 6 is mounted the drivepulley n.

One of the special features of our invention, which while giving themotor a fair degree of efficiency enables it to be cheaply manufactured,consists of the channelsha ed wheel-bucket 0 formed of sheet metal (asfor example, of galvanized iron) as shown in perspective in Fig. 3. Oneof these buckets or vanes is removed from the waterwheel in Fig. 1 toillustrate its mode of setting. A series of radial saw-cuts p are madeat regular intervals around the periphery of disk a, these being of ustsuflicient width to receive the edge of the bucket as shown, and afterthe latter is set therein it is secured in plfltce by a couple of nailsor tacks q on each si e.

To drive the motor we provide a water supply-pipe r at the upper cornerof the casing, this pipe ending in a nozzle .9 which directs a forciblejet of water upon the buckets 0. The bottom of the casing is braced bymeans of diagonal pieces t, which also serve to direct the exhaust orwaste water into the orifice a which is connected to the wasteplipe ofrom which the water may be conucted to a sink or other Waste-duct bymeans of a hose. The nozzle 8 is made removable so that the size may beadjusted to the ressure of water and power desired.

e recognize the fact that certain alterations which will readily occurto those skilled in the art may be made in the construction of our motorwithout departing from the spirit of our invention, and we wish itunderstood that all such modifications are included in our invention sofar as they lie within the reasonable scope of our claims.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is:

1 In a water motor, a water-wheel comprising a disk of soft materialsuch as wood,

a metal hub-piece to which said disk is secured, a pair of metalliclates or disks secured to 0 posite faces of said disk, and a pluralityof buckets secured to the edge of said disk.

2. In a water-motor, a wheel-disk of soft fibrous parallel grainedmaterial and having a plurality of narrow slots in the peripherythereof, a plurality of channel-shaped wheelbuckets of thin sheet metalhaving the same opening as the width of said disk and the center memberof the channel of each bucket set in one of said slots, and fasteningssuch as nails securing the flanks of said buckets directly to the sidesof saiddisk.

3. In a water-motor, a wheel-disk of soft fibrous arallel grainedmaterial and having a plura ity of narrow slots in the peripherythereof, a lurality of channel-shaped wheelbuckets 0 thin sheet metalhaving the same opening as the width of said disk and the center memberof the channel of each bucket set in one of said slots, and fasteningssuch as nails securing the flanks of said buckets directly to the sidesof said disk; in combination with a pair of sheet metal disks securedblylfastenings to the opposite faces of said 1s z.

4. In a water-motor, a wheel-disk of softfibrous arallel grainedmaterial and having a plura ity of narrow slots in the peripherythereof, a lurality of channel-shaped wheelbuckets 0 thin sheet metalhaving the same opening as the width of said disk and the center memberof the channel of each bucket set in one of said slots, and fasteningssuch as nails securing the flanks of said buckets directly to the sidesof said disk; in combination with a pair of sheet metal disks secured bya fastening to the opposite faces of said disk, a hub-member upon whichsaid disk is centered and secured, and a workingshaft upon which saidhub-member is centered and secured.

5. A water-motor comprising in combination a rectangular frame of softfibrous parallel grained material such as wood, a air of sheet metalplates closing the sides t ereof, a pair of central cross-bars at thesides of said sheet metal plates, bearing-blocks carried by saidcross-bars, a shaft rotating in said bearing-blocks, a disk-wheelmounted on said shaft inside said frame, water-vanes or buckets carriedon the periphery of said disk, a water-nozzle directed against saidvanes or buckets, and a waste-pipe adapted to withdraw the exhaust waterfrom the lower end or side of said frame, substantially as described.

6. A water-motor comprising in combination a disk-wheel havingperipheral buckets, a frame surrounding the periphery of the disk onlyand in the lane thereof and open at both sides; a pair of removableplates flanking the respective faces of the disk and closing the sidesof said frame, said Wheel being mounted on a shaft assing throughopenings in said plates, an a water-nozzle adapted to direct the wateragainst said buc ets.

7. In combination with a disk-wheel having peripheral buckets, arectangular frame surrounding the periphery of the disk in the planethereof and comprising four wooden strips secured together end to end;rectangular side-plates of sheet-metal covering the respective sides ofsaid frame and completely inclosing the wheel; and means independent ofsaid side-plates for supporting the shaft of said wheel which passesthrough holes in the center of said plates.

In witness whereof, We have hereunto set our hands this twenty-first dayof March, 1907.
